X-ray diffraction is one of the most powerful tool for identifying unknown crystalline phases. Many considerations and implications rest on the XRD results collected in terms of designing better materials or making decisions on your process control. What would your conclusions be if you notice peak shifts or peak broadening in your sample? During our work with numerous clients, we've noticed that the majority of poor XRD patterns is the result of poor XRD sample prepartation. Look forward to practical tips shared by Malvern Panalytical's senior XRD application specialist, Dr Daniel Lee during this webinar.

During this webinar, he shares tips relating to the optimal particle size, how to properly grind powder samples, choice of sample holder for situations like limited powder samples and more. Look out for our upcoming series of webinars on "Better XRD data quality results and interpretation".
